Organizations configuration

[xgp]

Allow global configuration of organizations features. Currently needed are:

• do/don't create org admin user
• allow shared idps
• ?

Path /realms/{realm}/orgs/config

Body (also the default values):

{
  "createAdminUserEnabled": true,
  "sharedIdpsEnabled": false
}

Methods:

• GET shows the config. Requires view-organizations realm-management role.
• PUT updates the config. Requires manage-organizations realm-management role.

---

We need to update the organizationCreation method in OrganizationResourceProviderFactory to check createAdminUserEnabled before creating the default organization admin user.

Will need a UI? Perhaps a modal off the action menu in orgs list page.
